- Page 4 A. Inspection of external leakage 1. Deep - groove ball bearing and rotary shaft lip seal on turbine shaft 1.1 Leakage on relief well In case there is a recognisable leakage on the relief well or in the turbine housing, it must be looked for the reason of the malfunction in the rotary shaft lip seal.
- Page 5 2. Repair of turbine bearing and rotary shaft lip seal In case it appears such a problem on your Tracker, the repair has do be done in the accomplish manner. Dismantle bonnet (BTV784337), gearbox cover (BTV784342) and plastic wheel (ZK3794434, screw axle BTC584383 and hub cover ZK3794435) completely.
- Page 6 Adhere turbine wheel (BTV784312) with the left hand and remove screw for turbine shaft turbine shaft (BTC484330) M10 from turbine shaft. Screw for turbine shaft BTA484370 Turbine shaft BTC484330 Clamping sleeve ZD1593196 Turbine wheel BTV784312 Beat back clamping sleeve (ZD1593196) with punch drift 4mm (standard tool). Pull out turbine wheel (BTV784312) with turbine shaft (BTC484330).
- Page 7 Beat out shaft seal packing (ZK0994377) together with guide bush for turbine shaft (BTC584388). In case grooved ball bearing (ZK1994372) is still complete: drive out with help of pressure bolt No.1 (BTC584431) to gear case. In case deep grooved ball bearing (ZK1994372) is broken (individual parts): Ball bearing remover ZB1198227 Outer ring ZK1994372 Pressure bolt 1 BTC584431...

- Page 11 Screw tightly cover for turbine shaft (BTC684371) with grooved ball bearing (ZK1994372) (3x ZD0293188) Screw for turbine shaft BTA484370 Cover turbine shaft BTC684371 Cylinder head screw ZD0293188 Turn turbine shaft and gear 1 in that way that the boreholes are congruent. Drive into clamping sleeve (ZD1593196) with punch drift 4mm, deeper than the dedendum.
- Page 12 Unscrew screw for turbine shaft (BTA484370), adhere turbine wheel with the left hand and tighten screw with 9-10Nm. If the clamping torque is to small a leakage on the turbine shaft arise; thereby the deep groove ball bearing is destroyed. Before screwing on turbine cover, lubricate face surface of the turbine housing with acid free grease.
- Page 13 Tighten turbine cover Assembly trip lever, but it must has at least 2mm clearance Axial clearance Assembly wheels, gear cover and cover to the unit.
- Page 14 Annotation Shim (BTK484374) is not necessary any longer (old type), if the new screw for turbine shaft (BTA484370) is used. For this repair following pieces are to be ordered: 6 pieces deep grooved ball bearing ZK1994372 1 piece shaft seal packing ZK0994377 1 piece guide bush for turbine shaft...
- Page 15 B. Examination of cable and cable drum 1. Examination of cable Cable should be examined once a month, check if plated bands are broken. (Only on steel cable). Hoisting drum should be replaced in case of any broken plated bands. Damages of the cables can occur when the cable is coiled beside the drum.
- Page 16 • Lead in the cable into the cable guide, trip lever and limit stop. In the end make a bow with a cable robe clip. Cable guide Please note, that spring and Teflon disk (drum brake) between cable drum and locating bearing are assembled on the shaft.
- Page 17 C. Examination of ball valve (only for Tracker) Examine ball valve for leakage After process of surface irrigation it is to examine, whether the ball valve is tight. Especially after the frost period, after this time it can occurs that the ball valve is burst. 2.
